Part number / identifier for PSX Parallel port

Post by moddy » September 20th, 2018, 10:51 pm

Hi,

I'm new to the whole PSX hacking scene, so hello! I got a bit nostalgic recently and bought a PlayStation, then thought it'd be kinda fun to understand the hardware a bit better, and perhaps have a go at writing some software.

I've been trying to find out what the part number for the parallel io connector is, I've seen a few posts on different boards that it has been figured out (although may not be in production) and I'd love to know what it is. My google fu has failed me..

Thanks!

I'm a bit confused. What exactly are you looking for? Do you have a newer model playstation that lacks the parallel port and you're looking to add one or are you just looking for a pinout of the port?

There is no part number for the parallel port. It was a custom connector used by Sony with a similar design to an old SCSI connector. The only company manufacturing this connector is Cybdyn Systems which they use with PSIO.
Development Console: SCPH-5502 with 8MB RAM, MM3 Modchip, PAL 60 Colour Modification (for NTSC), PSIO Switch Board, DB-9 breakout headers for both RGB and Serial output and an Xplorer with CAETLA 0.34.

PlayStation Development PC: Windows 98 SE, Pentium 3 at 400MHz, 128MB SDRAM, DTL-H2000, DTL-H2010, DTL-H201A, DTL-S2020 (with 4GB SCSI-2 HDD), 21" Sony G420, CD-R burner, 3.25" and 5.25" Floppy Diskette Drives, ZIP 100 Diskette Drive and an IBM Model M keyboard.

Can some replacements be bought from them ?
I have a few Xplorer carts i'd like to refresh that part (usually left/right sides broken).

Apologies if I wasn't super clear, I already own an SCPH-5502 and I wanted to try interact with the parallel port. Ideally I don't want to desolder the connector on the Playstation board, and I don't want to deconstruct something with that port (say a gameshark) to get one because I don't like tearing apart retro hardware unless there is no other way. There is a limited supply after all :).

I'm pretty good with hardware and software but I am still a noob on doing anything with the playstation. Initially I was hoping to grab a connector and make a breadboard adapter so that I can poke and prod a bit more (that port looks super powerful). Eventually was hoping to write some software.

That's a bummer.. I saw some reference suggesting Sony may have based it off an existing connector.. but it was a super old message and no follow up. Bummer!

I would also be interested if this was an option.
